4 Claims.

This invention relates in general to a package for tea, coee or other substances to facilitate handling and infusion thereof.

One object of the invention is to provide an infusion package of this character which shall include a novel and improved construction and combination of a porous, liquid-pervious container for tea leaves or other substances to be infused, and a non-porous or liquid-impervious tab or cover sheet secured to said container in normally side-by-side or overlying'relation thereto and capable of being folded, bent or swung with respect to the container so as to serve as a handle for agitating the container in a liquid, as with a stirring action, and for hanging the container on the edge of a cup, other liquid receptacle, or support.

A further object is to provide such a package wherein said tab or cover sheet shall be of such size, shape and material as to be capable of receiving printing impressions and serving as -a label for the package.

Another object is to provide an infusion package of this character wherein the container shall be formed of soft, flexible, porous material and the tab or cover sheet shall be formed of relatively stiff but preferably ductile material, such as metal foil or synthetic compositions that are inert in and will not affect or be affected by the liquid used in the infusion process, whereby the tab or cover sheet shall effectually serve as a label, as a handle for agitating the container in a liquid and as ahanger for supporting the container completely immersed in an infusion liquid. 35 Other objects, advantages and results of the invention will appear from the following description when read in conjunction with the accompanying drawings in which Figure 1 is a `perspective view of an infusion o package embodying my invention.

Specifically describing the embodiment of the invention illustrated in Figures 1 to 6 inclusive, the package includes a container A for the ini'u- 30 sible substance such as tea or coffee, said container being of any suitable shape and size and formed of any suitable material. Preferably the container is thin, approximately fiat and rectangular, and is formed of a known tough, highly porous paper which is also used for many other purposes, for example as a lter.

.The sheet of paper I may be folded in any suitable manner to form the container, but as shown,

vthe sheet is folded longitudinally as indicated at 40 2 and 3 with its'edges overlapping and secured together at l. The container may or may not have gussets 5 as desired. The free edges of the sheet at opposite ends of the container are secured together as by crimping indicated at 3, 4,5 preferably with a suitable adhesive between the overlapping plies of the sheet.

The container has secured thereto one or more tabs or cover sheets. As Ishown in Figures 1 to 6 inclusive, the cover sheet B is folded inter- 50 mediate its length about one edge oi' the container A as at I and secured to the container in any suitable manner. Preferably the sheet is crimped upon the container as indicated at 3, the crimping operation being either simultaneous with the formation of thejcrimps 9 or later, as

preferred. The tab or' cover sheet B is preferably formed of a non-porous; semi-stiff material capable of being bent and which is inert in and will not affect or be affected by the liquid used in the infusion process. As shown, the cover sheet B is formed of metal foil.

In its normal condition, the cover sheet B has its two portions 9 and I'0` at opposite sides of the fold Tnormally disposed in side-by-siderelation to the container A, and the edges of the portions 9 and I 0 may project beyond the corresponding edges of the container so that the container is substantially enclosed and protected by the coverf It is also desirable that the'cover be of such a nature that it may receive printing impressions or other inscriptions so as to serve as a label for the package.

It will be observed that the portions 9 and III are connected to the container in hinged relation thereto, and that these two portions may be swung or folded away from the container and to- 4ward each other, beyond the edge of the container to which the cover is attached, as shown in Figures 5 and 6. With the cover portions 9 and I0 in this position they may be gripped between the thumb and index finger so as to serve as a handle for the container A for example, for the purpose of agitating the container in the infusion liquid 'C in a suitable receptacle such as a cu'p D. 'I'his function of the package is illustrated in Figure 6 of the drawings. By simply bending the cover portions 9 and II), a hook may be formed as indicated at II in Figure 7 which may be utilized for suspending the package on the edge of the receptacle D or other suitable support.

It will ,be observed that the semi-stiffness of the cover portions 9 and I0 will provide adequate support for manipulating andsuspending the package as described, but if desired, the cover portions 9 and I0 may be further folded, for e'xample as shown in Figures 8 and 9, so as to provide in effect a tubular handle I2. Other ways of folding the cover portions 9 and I9 will readily occur to those skilled in the art.

' In many cases the cover portion may be applied to only one side of the container A, as shown in Figures 10 and 11, where the single cover sheet or tab E has one edge portion folded over or embracing one edge of the container A and is secured thereto in any suitable manner as by crimping I3. The cover sheet E may serve in the same manner as the cover sheet B above described.

It is also possible to utilize a smaller tab, as shown in Figure l2, where the tab consists of a narrow strip F of suitable material secured to one edge of the container A in any suitable manner. If desired, two strips, one'at each side of the container, may be used.

Figure 13 shows a somewhat similar form of package wherein the tab G consists of a narrow strip of material which is longitudinally reenforced by corrugations I4. In both the forms shown in Figures 12 and 13, the tabs F and G may be swung with a hinged action relative to the container A beyond the edge of the container to which the tab is connected so as to serve as a handle or a supportfor the container.

If desired, the tab G also may have an ear Il.

struck up therefrom to take over the edge of the cup D or other support for suspending the container on the cup or support.

In Figure 13 I have also shown another form of container, the container consisting of two sheets I6 of material in superposed relation and secured together at their edges by crimping I1, wh or without adhesive, as may be more suita e.

Another form of cover sheet is shown in Figures 16 and 17 where the sheet comprises a thickness of cardboard or other similar material I8 on opposite sides of which are permanently secured layers I9 of .metal foil or other suitable material that is inert in and will not affect or be affected, by the infusion liquid. The layers I9 will prevent contact of the layer I8 with the infusion liquid.

While I` have shown and described several different forms of the invention, it will be under. stood that this is primarily for the purpose of illustrating the principles of the invention, and that the form and structure of the container A -and the various tabs and cover sheets, may be widely modified and changed by those skilled in the art without departing from the spirit or scope of the invention.

Having thus described my invention, what I claim is:

1. An infusion package comprising a thin, approximately fiat, flexible, soft, porous-walled container for an infusible substance, and a sheet of semi-stiff non-porous material normally disposed in side-by-side relation to said container and having a portion folded and crimped about the edge of the container in embracing relation thereto, whereby said sheet protects and reenforces said container during handling and may be bent at said crimped portion relatively to said edge of the container to serve as a handle and hanger therefor.

2. The infusion package set forth in claim l wherein said sheet is composed of metal foil and has its edges juxtaposed to the edges of the container.

3. An infusion package comprising a thin, approximately fiat, flexible, soft and porous-walled container for an infusible substance, and a cover consisting of a sheet of semi-stili, substantially non-porous material capable of being bent, said sheet being folded intermediate its length about one edge of said container and secured thereto with the edges of said sheet projecting beyond the edges of said container, whereby said cover protects said container, serves as a label, and may be bent or folded relatively to the container to serve as a handle and hanger therefor.

4. The infusion package set forth in claim 3 wherein said cover is composed of metal foil and is crimped upon the container at the fold intermediate its length. A
